Integrated circuits are an indispensable part of modern electronic technology, often containing many complex circuits and functions. Therefore, various tests are required during production and maintenance to prevent defective products from entering the market. The following is a detailed introduction of which tests are included in integrated In-circuit testing.

1. Functional testing

The function test of integrated circuits is one of the most basic tests, which is usually used to test whether the basic functions of integrated circuits are normal. When conducting functional testing, it is necessary to connect the integrated circuit to the testing equipment and test whether the output of the integrated circuit meets expectations by inputting some signals. If the functional test of an integrated circuit fails, further troubleshooting and repair are required.

2. Performance testing

Performance testing aims to verify whether the performance of integrated circuits meets the requirements. This type of testing evaluates the speed, throughput, latency, and other performance indicators of integrated circuits. In performance testing, the testing program runs various test cases to check whether the performance of the integrated circuit has reached the expected level.

3. Electrical parameter testing

Electrical parameter testing is one of the tests used to test the electrical characteristics of integrated circuits. These tests usually include tests on input voltage, output voltage, current, power, and other aspects. When conducting electrical parameter testing, it is necessary to use testing equipment to simulate different electrical signals and test whether the response of the integrated circuit meets expectations.

4. Temperature test

Temperature testing is one of the tests used to test the performance of integrated circuits at different temperatures. The performance of integrated circuits usually changes with temperature, so temperature testing is very important. When conducting temperature testing, it is necessary to expose the integrated circuit to different temperature environments and test whether the response of the integrated circuit meets expectations.

5. Environmental testing

Environmental testing aims to verify the performance of integrated circuits under various environmental conditions. This test evaluates the performance of integrated circuits under the influence of temperature, humidity, vibration, and other environmental factors. In environmental testing, the testing program will simulate various environmental conditions, such as high temperature, high humidity, low temperature, vibration, etc., to check whether the integrated circuit can work properly in various environments.

6. Leak testing

The purpose of leak testing is to test whether there is a leak in an integrated circuit. Mistesting refers to defects or errors that are not discovered during the production process. In leak testing, the testing program runs special test cases to check for any missing tests in the integrated circuit.

7. Reliability testing

Reliability testing is one of the tests used to test the reliability of integrated circuits. Integrated circuits may be affected by various factors during use, such as voltage fluctuations, temperature changes, mechanical stress, etc. Therefore, reliability testing is necessary to evaluate the reliability of integrated circuits. When conducting reliability testing, it is necessary to expose the integrated circuit to different environments and test whether the response of the integrated circuit meets expectations.
